Figure 3 isaplan yiew of the plate which is wrapped around the frame.

I first take a series of rings, a a, and connect the same at suitable distances apart by means of ribs or stays b b, forming a round or polygonal-shaped frame,

The plate A- is secured to the coupling Gland point v B by rivets, or other suitable means, and in some cases the frame a b may not bc secured to said point and coupling unless specially desired.
